Support using tags as only source for version

[mortenn]

Thanks for your efforts thus far!

It would be great if I could use this tool in pipelines without needing to add additional artifacts to the tree.

To this end, I would like to see the tool read tags in the tree, and combine that with "git height" to spit out a version number.

Say the commit is tagged v1.0.0; version should then simply be 1.0.0
Another commit is made, the version would then become 1.0.1

Cheers, Morten

That would lead to one commit building as one version one day, and as another version another day, merely due to the addition of a tag to the repo. That runs counter to the NB.GV philosophy, which is that a given commit only produces one (or two, due to the PublicRelease flag) version.

But there is a community out there that wants what you're asking for. I suggest they use GitVersion, which uses branch names, tag names, and PR environment variables to compute the version.
